Tricone Bit Lefapheng la Oli le Khase
Trione bit e qapiloe ke moenjiniere oa Hughes le Ralph Neuhaus 'me e ne e le phetoho ea mochine oa pele oa li-cone tse peli oa Baker Hughes. Tricone bit ke karoloana ea ho phunya e nang le hlooho e arotsoeng likarolo tse tharo tse kholo. Karolo ea tricone e na le li-cones tse tharo tse potolohang tse sebetsang ka hare ho tse ling tse nang le mela ea eona ea ho itšeha meno. Li-roller-cone bits li sebelisetsoa ho phunya libopeho ho tloha ho bonolo ho ea ho thata. Meetso e bonolo e sebelisa likotoana tsa meno a tšepe le tungsten carbide e thata.
Molemo o moholo oo likotoana tsa trione li nang le oona ho feta ntho leha e le efe e 'ngoe ea ho phunya ke teko ea nako. Li 'nile tsa hlahlojoa hangata ho paka hore ke tsona tse molemohali ho laola maemo a thata. Bokhoni ba li-Tricones ba ho sebetsana le libopeho tse bonolo le tse thata li ba fa bonolo boo likarolo tse ling tsa ho cheka li se nang tsona.
PDC Bit indastering ea Oli le Khase
Li-bits tsa PDC li fumana mabitso a tsona ho tsoa ho li-compact diamonds tsa polycrystalline tse sebelisetsoang sebopeho sa tsona sa ho seha. PDC Bit ke boro e kentsoeng ka lithapo tsa litaemane tsa indasteri ho fapana le meno a tšepe a thata.
Lisebelisoa tsa PDC li ile tsa ntlafatsoa lilemong tsa bo-1970 'me ea e-ba e' ngoe ea likotoana tse ratoang ka ho fetisisa lefatšeng. Moqapi o na le lihlooho tse tsitsitseng 'me o entsoe ka ho kopanya litaemane tsa maiketsetso le tungsten carbide ka mocheso le khatello. Likotoana tsa PDC li phunya kapele ho feta likotoana tsa tricone 'me li tseba ho kuta lejoe, leha likotoana tsa trione le PDC li na le libaka tse arohaneng indastering ea ho cheka. Meralo ea morao-rao ea PDC e kenyelletsa meralo ea seha se bilikaneng kapa ea asymmetric, mehele ea gauge, le meralo ea li-hybrid cutter.
Leha likotoana tsa PDC li ntse li tsebahala, likotoana tsa trione li ntse li susumetsa merero e mengata e fapaneng ea ho cheka. Tsena li akarelletsa lehlohlojane, dolomite le mokoetla o thata. Kaha liphetoho ho PDC ha li bontše thahasello leha e le efe libakeng tseo, li-tricone bits li tla tšoara libaka tseo nako e telele.
Phapano ke Efe?
Phapang e totobetseng ka ho fetisisa pakeng tsa tricone bit le PDC drill bit ha se karolo e tsamaeang ho PDC Bit.
Likotoana tsa Tricone li na le li-roller cones tse tharo (likarolo tse tsamaeang), 'me li hloka li-bearings tse tlotsitsoeng le polokelo ea mafura. Ha likotoana tsa tricone li sebelisoa mererong e meholoanyane, hoa hlokahala hore ho be le tiiso e ts'oarellang e le hore li-driller li ka thibela litšila hore li se ke tsa baka ho emisa ho potoloha.
Li-cutters tsa PDC tse tsitsitseng li tiile 'me ha li na likarolo tse tsamaeang. Likotoana tsa PDC li entsoe ka ho kopanya litaemane tsa maiketsetso tse entsoeng hantle le tungsten carbide tlas'a mocheso o phahameng haholo le khatello.
Mofuta oa ho itšeha oa PDC le Tricone o fapane hape. PDC e kuta lefika ha trione e pshatla.
Tricone bit e hloka WOB e batlang e phahame ho sebetsa hantle. Ho seng joalo, lisebelisoa tsa eona li ka 'na tsa tsofala pele ho nako.
Kakaretso:
PDC bit ke khetho e ntle bakeng sa maemo a mang a sebopeho. Likotoana tsa PDC li sebetsa hantle lejoeng le kopaneng, le tšoanang, joalo ka shale, sandstone, limestone, lehlabathe le letsopa. Ha o sebetsa ka majoe a boletsoeng ka holimo, o ka leka PDC bit e le tharollo e potlakileng, e sireletsehileng le ea moruo. Ho seng joalo, Tricone ke khetho ea hau e ntle ka ho fetisisa.
